You are wrong to want to do this.

Consider the following scenario:
=========================================================================
A file, which is infected with a Y-system-specific virus, arrives on 
your machine, and passes all the checks because you have removed its 
fingerprints from the scanner.

You then copy that file onto a USB stick and give it to a friend who 
runs a Y-system, and they put it in their machine...

Shortly after this, their bank-account is drained, their identity is 
stolen, and it is your fault.
=========================================================================

We scan files for any and all sorts of virii, because we don't know 
where the files may end up.
